Frequently Asked Questions

The Baby Name Uniqueness Analyzer can determine how likely a person with a given name is to encounter another individual with the same name.

With the latest trend of selecting unique and unusal names,
popular names are not as popular as they once were. The probability that parents in 2017 name their
child Liam or Emma, the top boys' and girls' names, is only
1%. Twenty-five years ago the top boys' and girls' names were Michael or Ashley.
Back then, a baby had a 2.43% probability of being given either name. In other words, a child born today is over twice as likely to be given the current year's top name
than a child born twenty-five years ago. While this trend may be associated with the current generation of parents, it's been occuring for far longer. Only 4.3% of children born last year were given a name in the top ten.
In comparison, twenty-five years ago 9% of children would be given a name in the top ten, and 50 years ago
that number was 13.7%. A person born into our parents' generation is nearly three times as likely to be given a top
ten name than a person born into our kids' generation. As someone who had two other 'Sara's (spelled differently) in her kindergarten class, I am fasinated
that the probability of a kindergarden class of 35 in 2018 having any two children with the same name is only
44.8%. The probability of a kindergarten class having three children with the same name?
Just 1.4%. That doesn't mean it never happens. With so many kindergarteners in the US,
we estimate approximately 2,429 kindergarten classes across the country will have three kids with the same name.

Were there really ten boys named Sarah in 2015?
Looks like! Our data comes direct from the US Census Data,
and that's what the Social Security Administration (SSA) reports. With a 3,961,981 babies born in 2015, there's bound to be at
least a few reporting errors. There's also going to be a few really far out their names. There may have been 10 boys named Sarah,
but there were also 16 girls named 'Abcde'.

Hey, my daughter's/brother's/neighbor's name isn't on the list! What gives?
Congratulations on a super rare name! Your daughter/brother/neighbor is one of a kind! Or, more precisely, one of no more than 4.
The Social Security Administration (SSA) does not include baby names when fewer than five babies were given
the name.
